Detected package downgrade: Microsoft.NETCore.App from 2.1.3 to 2.1.0

I had a similar issue to you. Could not publish my project when I specified a runtime identifier.

The solution I got to work was to add in the following line to the *.csproj

true

After that line was added the project would publish correctly.

The below link references a downgrade issue between 2.1.1 and 2.1.0 but the solution worked the same.
